This paper focuses on modeling and parameter estimation for the electrohydraulic actuation system of an articulated forestry machine. The linear graph method is implemented in deriving mathematical models of the swing, boom and stick subsystems. Actuation dynamics are subsequently integrated with manipulator dynamics to result in a complete machine model.(More)
This paper focuses on the modeling, parameter estimation, and model validation in open and closed-loop of an experimental forestry ma chine manipulator. Symbolic Newton-Euler and linear graph methodologies are used in deriving mathematical models of the swing, boom and stick subsystems. Actuation dynamics are integrated with manipulator dynam ics to result(More)
